the instructor also forgot to mention that when the case is opened dust and dirt will go everywhere. i see they use a brand new one in the tutorial.

the instructor only missed the screw amount by three.

theres other tips the guy who did the instructions could have done like make sure parts are lined up including the new hose. to be honest the instructions are done half assed at best.

also i found the hose on ebay for 9 bucks and its much heavier duty than the junk one they put on originally.

no info on removing old hose and replacing w new one. also the top did not come off as described. i would give a 50% rating and thats generous.
